need some help

kl7pb
I want to be able to run my AL-811 Ameritron Amp with the K2/100 . I have an Ameritron buffer If need one. We live under an Aurora sponge in Alaska about 85% of the time 100 watts will not get you 100 miles. As an ARES Emergency Coordinator I need the power for our daily nets. How do I do this someone please. Tnx Rich

Re: need some help

Rich - Connect a cable with RCA male plugs on each end (typical audio cable
from a stereo) from the "Relay Out" RCA socket on the rear of the KPA100 to
the Antenna Relay socket on the rear of the AL-811 and follow the directions
in the AL-811 manual to tune the amplifier up!  Yes, the hookup really is
that simple!

If you DO NOT have the KAT100, then pushing the "Tune" button on the K2 will
give you about 20 watts (if the K2 Power control is advanced to above 20
watts - it will "time out" in a few seconds) to start the amplifier tuning
procedure.  You can repeat this as many times as you need to to get the amp
tuning "in the ballpark" - Since the AL-811 does not have an RF Output
meter, perhaps you can use an external one to see how the power increases as
you get close to the proper Tune and Load settings on the amplifier.  Once
you have the amplifier preliminarily tuned, then you can inject more rf from
the K2 by pressing in both the "Tune" button on the K2 and the "Display"
button on the K2 (button right above it) AT THE SAME TIME and adjusting the
Power control on the K2.  (If you feel comfortable doing so, you can start
with the K2 RF Power turned down to about 20 watts and not bother with the
"time out" feature of just pressing the "Tune" button as described in the
beginning of this paragraph.  Advance the K2's Power control until the
amplifier is properly tuned as per the manual.

If you DO HAVE the KAT100 connected then put it in the "Cal" mode to
accomplish the same thing. Be CAREFUL when pushing the "Tune" button on the
K2 as you can easily switch from Antenna 1 to Antenna 2!   73 es gud
